Answer:
The answer is 11.
Step-by-step explanation:
First, you put all of the numbers in order, from 7 - 19.
You find the median. You should get 11 and 11.
You add the numbers up to get 22 and divide by 2.

Answer:
x=2
Step-by-step explanation:
5x-1=3x+3
2x-1=3
2x=4
x=2
Answer:
x = 2
Step-by-step explanation:
We can say that both the triangles are congruent by the "if two angles of given triangles are congruent then the triangles are congruent" theorem, so we can set both equations equal to each other:
5x - 1 = 3(x + 1)
=> 5x - 1 = 3x + 3
=> 2x - 1 = 3
=> 2x = 4
=> x = 4/2
=> x = 2
Hope this helps!

ASAP ASAPPPPPPP!!!!!!!!
Answer:
135
Step-by-step explanation:
so we need to find the volume of the rectangle
V= L x W x H
V = [tex]2\frac{1}{4}[/tex] x [tex]\frac{3}{4}[/tex] x [tex]1\frac{1}{4}[/tex] = [tex]\frac{135}{64}[/tex]
so now we need to find the volume of the cubes
V = a^3
1/4^3 = 1/64
so:
135/64 ÷ 1/64 = 135
SO135 CUBES :)

Find the measure of x.
Answer:
C
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent
x is the angle between line with 3 strokes and 2 strokes
The corresponding angle is therefore ∠ C
∠ C = 180° - (63 + 29)° = 180° - 92° = 88°
Then x = 88 → C
Find the volume of the rectangular prism 16 ft 9 ft and 3 ft
Answer:
432
Step-by-step explanation:
Guys pls help me!!!!!
Answer:
2) y = 0.5^x
Step-by-step explanation:
Plug in x coordinates to see which equation makes up the graph. We can see that the y values lower even after using positive numbers so this eliminates the possibility of 1) as that would make the y values increase. Starting with coordinates (-1, 2), let's plug these into 2):
y = 0.5^x
2 = 0.5^-1
2 = 2
Correct
Use another pair of coordinates to see if it still works:
(-2, 4)
4 = 0.5^-2
4 = 4
It does!
Check the other equations just to make sure this is the only option:
2 = 5^(- - 1)
Negative + Negative = Positive
2 = 5^1
2 = 5
Incorrect.
2 = 0.5^(- - 1)
2 = 0.5^1
2 = 0.5
Incorrect.
This means our first solution is the only solution.
Look at the picture for the graph/question
A parabola is a U shaped graph and can be either upright ( u -shape) or upside down ( upside down u-shape)
The bottom right graph is an upside down I-shaped line so that is the parabola.
Answer:
Bottom right.
Step-by-step explanation:
The picture in the top left is a linear graph.
The picture in the top right is a graph of exponential growth.
The picture in the bottom left is a graph of the cube root function.
So we have the picture in the bottom left to be the parabola.
Solve for y -72=8(y-3)
Answer:
Step-by-step explanation:
y - 72 = 8(y - 3)
Distribute the 8 into (y - 3).
y - 72 = 8y - 24
Subtract 8y from both sides.
-7y - 72 = -24
Add 72 to both sides.
-7y = 48
Divide both sides by -7.
y = -48/7 or approxametly -6.9.
Proof:
y - 72 = 8(y - 3)
Substitute variable.
-48/7 - 72 = 8(-48/7 - 3)
Subtract.
-552/7 = 8(-69/7)
Multiply 8 by the inside term -69/7.
-552/7 = -552/7.
A box of candy has 8 caramels and 17 nougats. If Jose randomly takes 1 piece and then another piece without replacement, what is the probability that Jose drew 1 caramel and then 1 nougat?
hElP
Answer:
17/75
Step-by-step explanation:
The total number of candies = 8 caramels + 17 nougats = 25 candies
The probability that Jose drew 1 caramel and then 1 nougat without replacement = P(C) and P(N)
= 8/25 × 17/24
Further simplifying
= 1/25 × 17/3
= 17/75
Therefore, the probability that Jose drew 1 caramel and then 1 nougat without replacement is 17/75

Answer:
The bject will move forward
Step-by-step explanation:
When more than one force acts upon an object, the vector sum of these forces is the resultant force. When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. ... That is, there is zero acceleration.
